Note 29

The new gateway was written in assembly language running under the DEC Micro Operating System (MOS), and used LSI-11/03 or PDP-11/40 hardware depending on anticipated load.  This gateway replaced the earlier BBN gateway written in BCPL for the PDP-11. In a comparison test the BCPL gateway was able to process 50 packets per second and the Micro-11 gateway processed 100 packets per second. By February 16, 1982, the Macro-11 gateway was installed at 4 sites, as follows:
